Principles of Mixed-Initiative User Interfaces

Abstract:

Recent debate has centered on the relative promise of focusing
user-interface research on developing new metaphors and tools that
enhance users' abilities to directly manipulate objects versus
directing effort toward developing interface agents that provide
automation. In this paper, we review principles that show promise for
allowing engineers to enhance human-computer interaction through an
elegant coupling of automated services with direct manipulation. Key
ideas will be highlighted in terms of the Lookout system for
scheduling and meeting management.
